Answer:
Option (D)
Explanation:
Transverse waves are usually defined as those wave in which the particles within the medium vibrates perpendicular to the direction of wave propagation direction. These are comprised of crest and trough and also comprises the other properties of a wave such as amplitude, wave speed, wavelength, time period and frequency. For example, X rays, lightwave, and microwaves.
On the other hand, longitudinal waves are defined as those waves in which the particles present in the medium vibrate parallel to the wave propagation direction. For example, sound waves.
Thus, the correct answer is option (D).
